Next week is the girls' last ballet/tap class and they are preparing a mini performance. They are performing to a song from the movie Tangled, which have they have seen many many times and have actually memorized the song. So as they practice, they are both mouthing the words. J turned to K and mouthed something to her. I don't know what it is but I'm pretty sure it's about the song.
(K is wearing all black, J is wearing black top with pink/blue skirt.)
